The Sand Pebbles
Comrade X. Clark Gable in 1940 Moscow.
The Search. Montgomery Clift is a GI who reunites a DP with his mother. Filmed in postwar Germany.
The Big Lift. Montgomery Clift in postwar Berlin.
The Third Man. Joseph Cotton, Orson Welles, Trevor Howard. Black marketeeers in postwar Vienna.
The Journey. Yul Brynner as a Soviet officer in Cold War Hungary. With Jason Robards and Deborah Kerr.
Mission to Moscow. US pro-Soviet propaganda. This one is a howler!
Spartacus
Gladiator has that great Romans vs. Germanic barbarians battle at the start.
I nominate Johnny Got His Gun.
These are the versions I’m using for those listed. Where you see blanks it means I didn’t find a “war movie” to match, so I need your help on those.
If I didn’t provide the IMDb link and release date it means that one is already on my listing, which I will update and post later, so as not to have too many longish posts of the whole enchilada.
Thanks to all for the great suggestions. Rave on!

I’m guessing that should be Unbroken (2014)
Looks good to me, too. I’ll add it in in any case. Thanks.
More for trivia value than anything else, and I probably won’t add it to the list, but I’m curious if any of you have ever seen…
Yellowneck Yellowneck (1955) - IMDb (1955)
… a Civil War thing I saw as a teenager and some of the scenes and dialog are with me to this day!
Just out of curiosity again, has anybody tried to come up with a list of conflicts that our selections represent?
I don’t see Blackhawk Down on the list! :eek:
Let’s see …
Somalia (that wasn’t a war, was it? 
),
Cold War (no ***Rambo ***movies either! 
),
Vietnam,
Korea,
WWII,
WWI,
Age of Imperialism,
American Civil War,
Crimean War,
Russian “Patriotic” War of 1812,
American Revolution,
French and Indian (Seven Years’) War (no Barry Lyndon?),
Elizabethan Era,
Roman Empire,
Greek Wars (300 Spartans, Alexander the Great; I prefer the one with Richard Burton) …
Have I missed any? :dubious:
What the hell, throw in The Buccaneer (Yul Brynner, Charlton Heston, EG Marshall, and Claire Bloom) for our War of 1812. 
Whoops! :smack:
Bolshevik Revolution,
Russian Revolution of 1905,
Boer War,
Boxer Rebellion,
American Indian Wars,
Texas War of Independence,
100 Years’ War.
Any more???
Drums along the Mohawk, Northwest Passage, and Last of the Mohicans are all French and Indian/American Revolution movies.
See Post #144, (2001), please.
Rest of your post looks great! Lots of folks chopping up other folks, for sure.
Inter- and Postwar Periods (1920s and '40s),
WWI Arab Revolt,
Zulu Wars,
English–Scottish Border Wars,
Novgorod vs Teutonic Knights.
Are there no films out there about the English Civil War? :dubious:
Is Khartoum on the list?
The African Queen.
They just keep coming…
Another Colditz movie (the one I was thinking of). John Mills and Guy Hamilton, who directed four Bond films including Goldfinger:
Ice Cold in Alex with John Mills and Anthony Quayle.
Napoleonic Wars too.
I don’t see Counterpoint (Charlto Heston, Maximillian Schell) on the list either.
Does The OdeSSa File count? Lots of ONs in that one!
Taras Bulba with Yul Brynner, Tony Curtis, and Christine Kaufman. 16th-century Cossacks vs Turks and Poles.
